This reverts commit b723d21. Simplifying the track names might make them harder to read, so I'm kicking this can down the road for now.

When you pin a track, it doesn't show any context about where it came from. For process-scoped tracks such as thread state or counter tracks, their process context is lost.
The fix is to make pinned tracks show the full path, but first we need to change how pinned tracks work. Currently, pinned tracks are a separate mini workspace, and each TrackNode in it is a standalone TrackNode. When we pin, we take a complete copy of the node and add that copy to the pinned tracks workspace.
This patch changes how this works, so that pinned tracks are actually references to TrackNodes in the workspace.
This does also involve changing debug tracks and some plugins which added tracks to the pinned area directly, as we now must add a track or group to the workspace first before it can be pinned, but the result is the same.
